  BY 
  HENRY 
  EDWARDS. 
  

  

  The 
  species 
  of 
  Papilio 
  composing 
  the 
  group 
  of 
  which 
  P. 
  Asterias 
  and 
  P. 
  

   zoHcaon 
  are 
  the 
  best 
  known 
  forms, 
  appear 
  to 
  have 
  obtained 
  their 
  largest 
  repre- 
  

   sentation 
  on 
  the 
  PaciSc 
  Coast, 
  as 
  the 
  whole 
  of 
  those 
  known 
  to 
  science, 
  with 
  the 
  

   exception 
  of 
  P. 
  Bairdii, 
  from 
  Texa?, 
  are 
  found 
  more 
  or 
  less 
  abundantly 
  from 
  

   Alaska 
  to 
  the 
  shores 
  of 
  the 
  Gulf 
  of 
  California. 
  That 
  these 
  insects 
  are 
  apt 
  to 
  

   run 
  into 
  varieties 
  there 
  can 
  be 
  but 
  little 
  doubt, 
  and 
  it 
  has 
  not 
  been 
  without 
  

   some 
  misgivings 
  that 
  I 
  have 
  ventured 
  to 
  add 
  another 
  to 
  the 
  list. 
  I 
  have, 
  how- 
  

   ever, 
  carefully 
  studied 
  all 
  the 
  examples 
  in 
  my 
  collection, 
  and 
  can 
  only 
  arrive 
  at 
  

   the 
  conclusion 
  that 
  I 
  am 
  justified 
  in 
  describing 
  the 
  following 
  as 
  a 
  distinct 
  

   species 
  : 
  

  

  Papilio 
  Pergamus. 
  Hy. 
  Edw. 
  nov. 
  sp. 
  

  

  J 
  . 
  Antennte 
  and 
  head 
  dull 
  black. 
  Thorax, 
  black, 
  with 
  the 
  palagiae 
  rather 
  

   dark 
  yellow, 
  orange 
  anteriorly. 
  Abdomen 
  black, 
  with 
  a 
  yellow 
  lateral 
  stripe, 
  

   becoming 
  obsolete 
  towards 
  the 
  base. 
  Feet 
  and 
  legs 
  entirely 
  black. 
  

  

  Pi-imm-ies. 
  Rich 
  velvety 
  black, 
  as 
  iu 
  Asterias. 
  A 
  row 
  of 
  eight 
  cream-yel- 
  

   low 
  sub-marginal 
  spots, 
  of 
  which 
  the 
  one 
  nearest 
  the 
  apex 
  is 
  the 
  largest, 
  and 
  

   almost 
  round. 
  The 
  second 
  is 
  also 
  nearly 
  round, 
  the 
  remainder 
  becoming 
  some- 
  

   what 
  lunate, 
  the 
  last 
  produced 
  into 
  a 
  point 
  posteriorly. 
  The 
  macular 
  band 
  is 
  

   composed 
  of 
  eight 
  spots, 
  the 
  smallest 
  nearest 
  the 
  costa, 
  and 
  gradually 
  increasing 
  

   in 
  width 
  to 
  the 
  interior 
  margin. 
  The 
  first 
  spot 
  is 
  oblong, 
  the 
  next 
  five 
  are 
  

   angular, 
  the 
  seventh 
  is 
  in 
  the 
  form 
  of 
  a 
  parallelogram, 
  and 
  the 
  eighth 
  is 
  a 
  

   longitudinal 
  streak. 
  Within 
  this 
  band, 
  and 
  closely 
  approaching 
  the 
  costa, 
  is 
  a 
  

   small 
  angular 
  patch, 
  and 
  a 
  very 
  few 
  yellow 
  scales 
  are 
  visible 
  in 
  the 
  middle 
  of 
  the 
  

   discal 
  cell, 
  and 
  near 
  the 
  base 
  of 
  the 
  wing. 
  Fringes 
  black, 
  with 
  indistinct 
  white 
  

   patches 
  between 
  the 
  nervules. 
  

  

  Secondaries. 
  The 
  macular 
  band 
  is 
  wider 
  than 
  is 
  usual 
  in 
  Asterias, 
  and 
  per- 
  

   fectly 
  straight 
  on 
  its 
  inner 
  edge, 
  so 
  that 
  when 
  the 
  wings 
  are 
  spread, 
  the 
  band 
  of 
  

   both 
  wings 
  presents 
  a 
  nearly 
  uninterrupted 
  straight 
  line 
  from 
  the 
  costal 
  nervure 
  

   of 
  the 
  primaries 
  to 
  the 
  anal 
  margin 
  of 
  the 
  secondaries. 
  The 
  first 
  two 
  spots 
  near 
  

   the 
  costal 
  margin 
  of 
  secondaries 
  are 
  almost 
  square, 
  slightly 
  notched 
  exteriorly. 
  

   The 
  third 
  is 
  oblong, 
  divided 
  by 
  the 
  discal 
  nervule. 
  Spots 
  four 
  and 
  five 
  are 
  

   somewhat 
  angular, 
  produced 
  a 
  little 
  outwardly, 
  thus 
  destroying 
  what 
  would 
  

   otherwise 
  be 
  a 
  perfectly 
  straight 
  band. 
  The 
  sixth 
  spot 
  is 
  almost 
  a 
  parallelo- 
  

   gram, 
  and 
  the 
  seventh 
  is 
  nearly 
  lunate. 
  The 
  submarginal 
  spots 
  are 
  five 
  in 
  

   number, 
  the 
  first 
  near 
  the 
  costa 
  a 
  mere 
  dot, 
  the 
  second 
  almost 
  oval, 
  and 
  

   the 
  other 
  three 
  lunate. 
  Margins 
  of 
  the 
  wing 
  broadly 
  notched, 
  emargina- 
  

   tions 
  yellow. 
  Tails, 
  wholly 
  black, 
  as 
  long 
  as 
  in 
  Asteriai, 
  but 
  slightly 
  nar- 
  

   rower. 
  Anal 
  spot, 
  large, 
  black, 
  wiih 
  iris 
  fulvous 
  anteriorly, 
  yellow 
  posteriorly. 
  

   Between 
  the 
  macular 
  band 
  and 
  the 
  submarginal 
  spots 
  are 
  some 
  bluish 
  scales
